Abstract

A variable speed manual transmission includes an input shaft 11 having a first drive gear 21a for low speed drive and a second drive gear 22a for high speed drive fixed thereon, an output shaft 12 located under the input shaft and in parallel therewith and having at least a pair of axially spaced change-speed driven gears 24a, 24b fixed thereon, a first countershaft 13 arranged in parallel with the input and output shafts and having a first driven gear 21b fixed thereon and continuously engaged with the first drive gear 21a, a pair of axially spaced low speed drive gears 23a, 23b rotatably mounted thereon and continuously engaged with the change-speed driven gears 24a, 24b on the output shaft, and a first synchronizer coupling 31 provided thereon to selectively connect the low speed drive gears 23a, 23b to the first countershaft, and a second countershaft 14 arranged in parallel with the input and output shafts and the first countershaft and having a second driven gear 22b fixed thereon and continuously engaged with the second drive gear 22a on the input shaft, a pair of axially spaced high speed drive gears 23c, 23d rotatably mounted thereon and continuously engaged with the change-speed driven gears 24a, 24b on the output shaft, and a second synchronizer coupling 32 provided thereon to selectively connect the high speed drive gears to the second countershaft.
